What is an intravitreal injection?

< 1 min read

An intravitreal injection delivers medication directly into the vitreous cavity of the eye. It is widely used to treat retinal and macular diseases.

Conditions Treated

Anti-VEGF drugs and steroids injected into the eye help manage wet age-related macular degeneration, diabetic macular oedema, retinal vein occlusions, and some inflammatory or infectious conditions. Repeated injections are often needed over time.

  • Given under topical anaesthetic with antiseptic preparation
  • A very fine needle passes through the white of the eye
  • The procedure is quick and generally well tolerated
  • Vision and retinal scans monitor response between visits

Risks and Follow-Up

Serious complications such as infection, retinal detachment, or significant bleeding are rare but important to recognise early. Patients receive clear safety-net advice about warning symptoms.

  • Mild redness, irritation, or floaters are common for a short period
  • Any increase in pain, marked redness, or sudden vision loss requires urgent review
  • Long-term treatment plans are individualised to disease activity
  • Stopping injections prematurely may risk vision loss in active disease
